1. Speakers - Connect speakers/subwoofers to these terminals. Be sure to check wire for proper

polarity. Never connect the speaker cables to the chassis ground.

2. +BATT (+12 Volt Power) - Connect this terminal through a FUSE or CIRCUIT BREAKER to the

positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery. WARNING: Always protect this power cable by installing a fuse or circuit breaker of the appropriate gauge within 18 inches (45cm) of the battery terminal connection.

3. Remote Turn On - This terminal turns on the amplifier when (+) 12 volt is applied to it. Connect it to

the remote turn on lead of the head unit or signal source.

4. GND - Run an equal gauge wire from the Ground (GND) terminal on the MTX amplifier to the

negative terminal on the battery. Use the shortest distance possible. It is always a good idea to replace the factory ground at this time with a cable equal or larger than the new amplifier power cable. CAUTION: Do not connect this terminal directly to the vehicle battery ground terminal or any other factory ground points.

5. RCA Input Jacks - These RCA input jacks are for use with source units that have RCA outputs. A

source unit with a minimum level of 200mV is required for proper operation. The use of high quality twisted pair cables is recommended to decrease the possibility of radiated noise entering the system.

6. Gain Control - The Gain control will match the amplifier’s sensitivity to the source units signal

voltage. The operating range is 5V to 200mV. NOTE: This is NOT a volume control.MTX.COM

7. Low Pass Filter Control (Mono Block) - This control is used to select the desired low pass x-over

frequency. The frequency can be adjusted from 40Hz to 220Hz for all bass mono models.

8. Subsonic Filter Control (Mono Block) - This control can filter out unwanted low frequency from

20Hz (OFF) to 50Hz. This function should only be used with vented enclosures.

9. Bass Boost Level Switch (Mono Block) - This switch can boost bass level by 0dB, 6dB, or 12dB.

The boost frequency is centered at 50Hz.

10. High Pass Filter (Full Range) - This controls the frequencies played for the front channels. Low

frequencies can be cut off from OFF to 200Hz. At OFF position, no low frequencies cut off, meaning full range.

11. X-Over Mode and Frequency Control (Full Range) - These controls allow control over the

frequencies played for the rear channels. There is an option for Low Pass, Full Range, or High Pass. In LP or HP mode, the crossover frequency can be tuned from 50Hz to 750Hz.

12. Power Indicator - This LED will light up when the amplifier is working properly.

13. Protection Indicator - The Red LED will light up and flash if there is a fault presented to the

amplifier. Please disconnect the amplifier and resolve the fault before reconnecting the amplifier. PANEL LAYOUT 4-Channel Amplifier Panel Layout

INSTALLATION AND MOUNTING

MTX recommends your new Thunder Marine WET Series amplifier be installed by a 12 volt installation specialist. Any deviation from specified installation instructions can cause serious damage to the amplifier, speakers and/or vehicle’s electrical system. Damage caused from improper installation is NOT covered under warranty. Please verify all connections prior to system turn on.

1. Disconnect the vehicle’s negative battery cable.

2. Determine the mounting place for your MTX amplifier. Keep in mind there should be sufficient

air flow for proper cooling. Mark the mounting holes from the amplifier to be drilled. Before drilling make sure all vehicle wires, gas lines, and gas tank are clear and will not interfere with installation. Drill the desired holes and mount the MTX amplifier.

3. Install a positive (+) power cable from the vehicle’s battery. Run the cable through

the vehicle and connect it to the amplifier’s (+BATT) terminal. Do not connect to the battery at this time. NOTE: Use only proper gauge wire for both positive and negative connections.

4. Install a circuit breaker or fuse within 18 inches of the battery. This effectively lowers the risk

of severe damage to you or your vehicle in case of a short circuit or accident. Make sure the circuit breaker is switched Off or the fuse is taken out of the fuse holder untill all connections are made. Now connect your positive power cable to the positive battery terminal of the battery.

5. Grounding - Run an equal gauge wire from the Ground (GND) terminal on the MTX amplifier to the

battery compartment. Once installation is complete you will attach this cable to the negative battery terminal on the battery in step 9.

6. Connect a Remote Turn-On wire from the source unit to the MTX amplifier’s (REM) terminal. If the

source unit does not have a dedicated Remote Turn-On lead, you may connect to the source unit’s Power Antenna lead.

7. Supply the signal to your MTX amplifier by connecting the signal cables using high quality RCA to

the corresponding outputs at the source unit and inputs of the amplifier.

8. Connect your speakers to your MTX amplifier’s speaker terminals using the correct gauge

speaker wire. Your MTX Thunder Marine amp can drive a 21 minimum load for optimum power.

9. Double check all previous installation steps, in particular, wiring and component connections.

Once verified, reconnect the vehicle’s negative battery cable, turn the circuit breaker On or place the fuse in the fuse holder. NOTE: Gain Levels on the amplifier should be turned all the way down (counter clockwise) before proceeding with adjustments.MTX.COM

INSTALLATION For proper perfomance and safety, MTX recommends installing an inline fuse per the owner’s manual instructions according to the following.
